The Indian stock market opened sharply lower on Tuesday, weighed down by selling across the board amid weak global cues. The benchmark indices, Sensex and Nifty 50, opened with a gap-down, extending losses for the second consecutive session amid renewed concerns over additional US tariffs on Indian goods, persistent FPI outflows, and the absence of fresh triggers for a rally that have resulted in fatigue among investors. The Sensex crashed 702.72 points, or 0.83%, to 84,399.97, while the Nifty 50 was trading 227.70 points, or 0.88%, lower at 25,732.85.
